SPECIFICATION formingpart of `Letters Patent No. 590,953, atea octber 5,1897. Application filed September 26, 1896. Renewed September 7, 11897.Serial Noi 650,845 (No model.)

Be it known that I, WILLIAM Il. BARNns, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Devices for Ati taching Furrlng to lValls; and I dohereby declare the following to be a full, clear, and exact descriptionof the saine, reference being had to the accompanying drawings, forminga part of this specification, and to the reference-numerals markedthereon.

My present invention has for its object to provide certain improvementsin the means for attaching furring-strips and lathing or other materialsto masonry, whereby the liability of its becoming loose isreduced to aminimum; vand it further has for itslobject to provide an improvedfurring-strip adapted for fireproof structures, well adapted for use inconnection with the attaching means; and the invention consists in thehereinafter-de-` scribed devices, the points of novelty being pointedout in the claims at the end of this specification.

In the drawings, Figure l is a sectional view of a brick wall, showingthe manner of attach'- ing a reproof furring and lathing; Fig. 2, a

horizontal sectional view through three furring-strips, showing themanner of securing them and the lathing also; Fig. 3, a perspective viewof one of the wall-`plugs removed;- Fig. et, a cross-sectional view ofthe same, and4 Fig. 5 a view of a modified formof securingnail. Fig. 0is a view of a modified form of plug. y l

Similar reference-numerals in the several figures indicate similarparts.

In securing furring-strips to masonry it has been customary to nail themto wooden plugs either builtin the wall between the stones or bricks ordriven in an aperture in the mortar, but this arrangement isobjectionable in that the plugs are liable to split or else they willshrink when securedin wet mortar to such 4an extent as to permit them topull out, and with the object in view of obviating these dificulties'and also of providing a means whereby/the strips can be readily adjustedto make the walls vertical I provide plugs or sockets of sheet metalsuitably roughened, corrugated, or crimped as to readily hold thesecuring-nails and adapted to be built in the wall or fastened inafterward. These plugs y consist generally of a socket l, of sheetmetal,

having circumferential corrugations formed in it, which will serve toengage ribs or projections formed upon the surface of the securing-nail2,` which is to be driven into it. As these sockets or plugs arepreferably arranged between theV bricks or stonesduring the formation ofthe wall the mortar, (indicated by 3,) extending between the exteriorribs, will effectually prevent the withdrawal of the plus" The socketscanbe easily and cheaply made of a singlepieceA of sheet metal, crimped,roughened, or corrugated and rolled up into the flattened tubular formshown in Figs. 3 an-d 4, and I prefer that the exterior end of thesocket be split for a short distance, as shown, and that the split ends4 project beyond the lface ofthe wall in order that the .furring-strips(indicated by can be made plumb by bending more or less one or both ofthe split ends 4:, so that the strips which abut against them may beheld a greater or less distance from the surface of the wall, as in Fig.l.

The shanks of the securingnails (indicated by 6) used in connection withthe plug are corrugated, roughened, or ribbed circumferentially, so astobind in the sockets, and while'they may be readily driven in theirwithdrawal is prevented, but the-heads of the nails may be of anydesired construction. For instance, when wooden furring-strips are usedthe nail may have an ordinary head, as shown in Fig`. 5; but when myimproved metal furring is used itis provided with a laterally-extendedhead, as shown in Figs. l and 2, adapted to project over the said strip.

The metal furring-strips, which are "partie ularly adapted for fireproofconstruction, are made of a single piece of sheet metal formed withdouble flanges 9 9 at each side and a central uniting weblO and resemblein. crosssection an I-beam. The outer flange at least ofthese strips isofcolnparatively thin or bendable metal, andthe laths ll, whether ofmetal or wood, .are to be secured by stapleshaped nails 12, driventhrough the lath with the legs on opposite sides of the flanges of thestrip and then set by a tool, such as 13, having a V-shaped jaw, whichwill bend the legs of the nail inward and also bend in the lateral edgesof' the outer flange 9 of the strip and possibly the metal lath as Well,as shown at the extreme right in Fig. 2,1irmly clamping the partstogether.

The Wall plugs or sockets can be made very easily and cheaply and arecapable of use for other purposes than the attachment of furring-stripsand may be used in connection with other forms of corrugated androughened nails, though I prefer to form the corrugations in the nailssmaller and closer together than those in the plug, so that the nailwill hold even if driven in half the distance between two of the plugscorrugations to tighten it.

While it is not essential that the plug shall be elliptical incross-section, I prefer this construction, as it affords greaterlatitude in the lateral location of the securing-nails, and suchaccuracy in placing the plugs in the Wall When building is not requiredas Would be if the nails fitted the plugs tightly at the sides, and Ihave found that the nails will be held suficiently'rigid for allpractical purposes.

In some instances I prefer to make the corrugations in the plugs at aslight angle to the ends, as shown in Fig. 6, and While this willprovide for holding the nails as described it Will also enable ordinaryscrews to be employed for holding the furring or other strips.

I claim as my inventionl. A tubular metal Wall-plug for receiving a nailand having a series of internal laterally-extending corrugations orribs, substantiall y as described.

2. A tubular wall-plug, adapted to be built into a Wall and composed ofsheet metal and having circumferential corrugations, subs'tantially asdescribed.

3. A Wall-plug, composed of a sheet of metal bent int-o flattenedtubular form and having external and internal circumferentialcorrugations, substantially as described.

4. A tubular metal Wall-plug, provided with circumferential corrugationsand having an adjustable outer end, substantially as described.

5. A tubular metal Wall-plug, provided with circumferential corrugationsand having the split outer end,substantially as described.

6. The combination with the sheet-metal Wall-plug, havingcircumferential corrugations, -of a corrugated secu ring-nail adapted tobe driven into the plug, substantially as described.

7. The combination with a Wall-plug, having a flexible portionprojecting beyond the Wall, of a metal furring-strip, having an outerflange, capable of being bent laterally, lat-hing, staple-shaped nailsfor securing the lathing to the strip, and a nail entering the plug andholding the strip, substantially as described.

8. A tubular metal Wall-plug consisting of folded and corrugated sheetmetal, the corrugations thereof extending at an angle to the plane ofthe aperture, substantially as described.
